Systems are provided for increasing an efficiency of an electric drive axle, and reducing a number of components and weight of the axle. In one example, an electric drive assembly comprises an electric motor having a rotor shaft supported by a first rotor shaft bearing and a second rotor shaft bearing; a gearbox having a layshaft layout, where at least one input gear of the gearbox is mounted on the rotor shaft; and a multi-piece housing, the multi-piece housing including a first housing section supporting the first rotor shaft bearing and a stator of the electric motor; the first housing section defining an inner boundary of a motor cooling jacket; and a second housing section partially overlapping with the first housing section, the second housing section partially enclosing the gearbox and partially enclosing the electric motor; the second housing section defining an outer boundary of the motor cooling jacket.
